I ordered a Blackhole Weaponry back in November, took a little over 3 months to receive because of the holidays. Took about another month to acquire the rest of the parts. Used a Bear Creek Aresenal side charging upper that’s was on sale for cheap! Currently using an ALG EMR V2 M-lok that I had to slightly modify to fit over the BCA upper. May change that later on. Also using my grandfathered MI pistol lower. So if I do choose, I can carry it same as a handgun. Have no intention of doing so, but nice to have the option. Lol. Still need to get a couple scopes for this and my other rifles, so it will be borrowing for the time being.

Yeah, it probably will have a pretty good bark. LOL I opted for Wilson's Q-comp. Figured it should help stay on target, and not kill me with the blast everytime I light one off. Another reason I went with it was because of the size. It only adds around 1.7" in length. I was looking at a couple other muzzle devices, one was Tromix's linear comp, but that would add about 2.8". At that point I think I would just run a 16" barrel w/ target crown as a rifle, and just skip the pistol build. Now if I build say a 10.5" for subs, than I will most likely run Tromix's linear comp.

Well took it to the range today to start breaking it in. Hornady factory ammo cycled no problem. I ran 225 FTX handloads using Lilgun. Took 38gr to get it to fully cycle. Has some pretty good recoil. Not terrible, but definitely more than if one was using a Ross brake. Also had some pretty good fire shooting out the muzzle, but not as bad as I thought. Sorry no groups or velocities, waiting until I break it in and the weather gets a little nicer.
